| 摘 要： | 根据2006年～2007年间在海南岛近岸海域进行的4个航次底拖网调查资料,分析了该海域鱼类物种组成和生物多样性特征。发现该海域鱼类种类较为丰富,调查共采集到鱼类292种,隶属于21目100科172属;其中暖水性种类数占83.32%,暖温性种类数占16.78%;与中国黄渤海共有种76种,与东海共有种220种,与南海大陆架、大陆坡和南海诸岛海域共有种分别为279种、42种和51种。鱼类优势种相对重要性指数（IRI）〉500]依次为发光鲷（Acropoma japonicum）、斑鳍天竺鱼（Apogonichthys carinatus）、黄斑鲾（Leiognathus bindus）、皮氏叫姑鱼（Johnius belengeri）、大头白姑鱼（Argyrosomus macrocephalus）、（Therapon theraps）、棕斑腹刺鲀（Gas-trophysus spadiceus）和麦氏犀鳕（Bregmaceros macclellandi）。以生物量为基础采用5个指数研究了该海域鱼类多样性现状,并采用季节更替指数（AI）和迁移指数（MI）对各季节鱼类群落的稳定性进行了分析。结果显示,该海域鱼类多样性水平较高,相邻季节的鱼类物种相似性也较高,随着鱼类的洄游,群落的稳定性出现较大波动。

| Abstract: | In base of the data of the trawl surveys from 2006 to 2007,we investigate the species composition and diversity of fishes in the coastal waters of Hainan Island.The results show that the area is rich in fishes with 292 species collected,belonging to 21 orders,100 families and 172 genera.Warm-water and warm-temperate species account for 83.32% and 16.78% of the total number of species,respectively.Mutual species in the coastal waters of Hainan Island with the Yellow-Bohai Sea and East China Sea are 76 and 220,respecitively;those with the continental shelf,continental slope and waters around islands in South China Sea are 279,42 and 51,respectively.The dominant fish species with IRI index 〉500 are： Acropoma japonicum,Apogonichthys carinatus,Leiognathus bindus,Johnius belengeri,Argyrosomus macrocephalus,Therapon theraps,Gastrophysus spadiceus and Bregmaceros macclellandi.Five indices of species diversity based on biomass are used for analysis,and seasonal dynamics of replacement index and migratory index are also applied to assess the stability of fish community.Results indicate that the fish diversity is high in the waters;the fish species in adjacent seasons are similar,and the community becomes unstable because of seasonal migration of fish. |
